Each board had two tenons, joined to one another. He made all the boards of the tabernacle this way.

He made the boards for the tabernacle, twenty boards for the south side southward.

He made forty sockets of silver under the twenty boards: two sockets under one board for its two tenons, and two sockets under another board for its two tenons.

and their forty sockets of silver: two sockets under one board, and two sockets under another board.

For the far part of the tabernacle westward he made six boards.

He made two boards for the corners of the tabernacle in the far part.
